Since ActiveSync GossipSyncers no longer synchronize our state with the
remote peers, none of the logic surrounding the round-robin is required
within the SyncManager.
This commit serves as another stop-gap for light clients since they are
unable to obtain the capacity and channel point of graph edges. Since
they're aware of these things for their own channels, they can populate
the information within the graph themselves once each channel has been
successfully added to the graph.
The check prevented the creation of port forwardings which were assumed
to be present already. After this change the port forwardings which
might have been removed from the NAT device can be re-created.
This commits exposes the various parameters around going to chain and
accepting htlcs in a clear way.
In addition to this, it reverts those parameters to what they were
before the merge of commit d107627145.
This commit adds optional jitter to our initial reconnection to our
persistent peers. Currently we will attempt reconnections to all peers
simultaneously, which results in large amount of contention as the
number of channels a node has grows.
We resolve this by adding a randomized delay between 0 and 30 seconds
for all persistent peers. This spreads out the load and contention to
resources such as the database, read/write pools, and memory
allocations. On my node, this allows to start up with about 80% of the
memory burst compared to the all-at-once approach.
This also has a second-order effect in better distributing messages sent
at constant intervals, such as pings. This reduces the concurrent jobs
submitted to the read and write pools at any given time, resulting in
better reuse of read/write buffers and fewer bursty allocation and
garbage collection cycles.
In this commit, we convert the server's Start/Stop methods to use the
sync.Once. We do this in order to fix concurrency issues that would
allow certain queries to be sent to the server before it has actually
fully start up. Before this commit, we would set started to 1 at the
very top of the method, allowing certain queries to pass before the rest
of the daemon was had started up.
In order to fix this issue, we've converted the server to using a
sync.Once, and two new atomic variables for clients to query to see if
the server has fully started up, or is in the process of stopping.
In this commit, we modify the server to serve the role as the agent
which will carry out the SCB restoration protocol if the Init/Unlock
methods include a set of channels to be recovered.
This commit increase the expiry grace delta to a value above the
broadcast delta. This prevents htlcs from being accepted that would
immediately trigger a channel force close.
A correct delta is generated in server.go where there is access to
the broadcast delta and passed via the peer to the links.

Previously it was difficult to use the invoice registry in unit tests,
because it used zpay32 to decode the invoice. For that to succeed, a
valid signature is required on the payment request.
This commit injects the decode dependency on a different level so that
it is easier to mock.
Previously a function pointer was passed to chain arbitrator to avoid a
circular dependency. Now that the routetypes package exists, we can pass
the full invoice registry to chain arbitrator.
This is a preparation to be able to use other invoice registry methods
in contract resolvers.
This commit modified the condition to whether drop an existing
connection to a peer when a new connection to this peer is
established.
The previous algorithm used public keys comparison for this decision
which determines that between every two nodes only one of them will
ever drop the connection in such cases.
The problematic case is when a node disconnects and reconnects in a
short interval which is the case of mobile devices.
In such case it takes as much as the "timeout" configured value for
the remote node to detect the "disconnection" (and try to reconnect
if this connection is persistent). In the case this node is also the
one that has the "smaller" public key the reconnect attempts of the
other node will be rejected causing it impossible to fast reconnect.
The solution is to only drop the connection if if we already have a
connected peer that is of the opposite direction from the this new
connection. By doing so the "initiator" will be enabled to replace
the connection and recconnect immediately.
In this commit, we also allow channel updates for our channels to be
sent reliably to our channel counterparty. This is especially crucial
for private channels, since they're not announced, in order to ensure
each party can receive funds from the other side.
Exposes the three parameters that dictate
the behavior of the channel status manager:
* --chan-enable-timeout
* --chan-disable-timeout
* --chan-status-sample-interval
